Aeroacoustic Noise Source Identification Using Irregularly Sampled LDV Measurements Coupled with Beamforming (AIAA-2011-2719)
(2011)This paper develops a technique which relates dynamic pressure measurements taken outside the hydrodynamic eld of a low speed jet to single point, one component velocity measurements taken within the jet using a Laser ... -
Design of a Kelvin cell acoustic metamaterial
(2020)Advancements in 3D print technology now allow the printing of structured acoustic absorptive materials at appropriate microscopic scales and sample sizes. Optimisation of parameter sets associated with a Kelvin Cell structure ... -
The Influence of Additive Manufacturing Processes on the Performance of a Periodic Acoustic Metamaterial
(2019)Advancements in 3D print technology now allow the printing of structured acoustic absorbent materials at the appropriate microscopic scale and sample sizes. The repeatability of the fundamental cell unit of these metamaterials ... -
